The 23-year-old student felt ill earlier this week and, on Tuesday, the decision was taken by show bosses to take him out of the villa

Fellow Islander, Dr Alex George announced to the other contestants that the Harry Potter fan had left the villa and would not be returning.

Speaking on Tuesday's show, the doctor said: "For personal reasons unfortunately he can’t continue or come back to the villa."

Following his departure, his partner Georgia said in the Beach House: “Obviously I was coupled up with him so obviously I came closer to him than most people in here but it wasn’t just that. He was actually my friend, my buddy.”

Alex added: “I’m obviously sad that Niall’s left the villa. We got on really, really well.

"He’s such a great guy. And I look forward to catching up with him and having some fun with him outside.”
